Union, OR
Union wildfire risk explained
Out of every US place USFS scores, Union lands at the 85th percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 1,523 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Union at the 85th national percentile — 1 points below its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
1,523 buildings are counted in Union, and 74.5% of them are Indirect exposure — ember-driven risk rather than the 25.5% in Direct exposure or the 0% rated Minimal.
Union against the rest of the country
Union ranks lower within Oregon (67th percentile statewide) than its 85th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Union ranks 4,644 for wildfire risk (1 is highest) and 9,069 by building count (1 is largest). Within Oregon alone, it ranks 139 of 420 places by risk. See the full county-by-county picture for Oregon on its state page.
What this risk score means for insurance
Because Union is in Oregon, a wildfire-hazard disclosure is legally required before a sale closes here — unusual nationally, since only these two states mandate it. Full detail in the disclosure-law guide.
What would actually reduce this score
With ember exposure the dominant pattern in Union (74.5% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
More on how this number was built
Union's 85th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what indirect exposure implies beyond Union, see the exposure-zones guide.
